+5
The formula for the ionic compound formed between Mg (magnesium) and As (arsenic) is Mg3As2. This is because magnesium has a +2 charge and arsenic has a -3 charge, so to balance the charges, two magnesium atoms combine with three arsenic atoms.
Yes, arsenate (AsO4^3-) is a polar molecule. This is due to its asymmetric shape and the unequal distribution of charge around the arsenic atom, resulting in a slight negative charge on the oxygen atoms and a slight positive charge on arsenic.
Arsenic trifluoride is a covalent compound since it is formed by sharing electrons between arsenic and fluorine atoms. It does not involve a transfer of electrons, which is characteristic of ionic compounds.
FeAs2 is the most common arsenide (míneral lollingite) it is not ionic. There are arsenide phases FeAs and Fe3As2 corresponding to iron(III) arsenide and iron (II) arsenide, again the bonding is not ionic.
Phosphite has an ionic charge of -3.
2As3+ + 3S2- ---------> As2S3
No, AsCl5 (arsenic pentachloride) is not an ionic compound. It is a covalent compound because it is composed of nonmetals (arsenic and chlorine) bonding through the sharing of electrons.
As is the element arsenic (it's not a compound). However, arsenic does bond with itself. Arsenic can be seen as As5+, As3+, As2+, As+, As3- or As3−. 4
The arsenic ion with a -3 charge has gained 3 electrons, giving it a total of 3 more electrons than the neutral arsenic atom. Arsenic typically has 33 electrons in its neutral state, so the arsenic ion with a -3 charge would have 36 electrons.
The ionic charge of stannous (tin) is typically +2.
The ionic charge of bromate ion (BrO3-) is -1.
Iodine typically has an ionic charge of -1.
